Okay, I'm learning my way through our AS400, V5R3. &nbsp;Right now I'm setting up a test environment. &nbsp;I've done the full backup and am restoring the libraries from the tape (tap02) with the test environment names. &nbsp;My full backup is on two tapes. &nbsp;The backup was completed on 7/17/07. &nbsp;Because the RSTLIB function seems to shut down jobs necessary for us to run our daily environment I'm doing this after hours. &nbsp;Last week I restored 7 libraries with no problem. &nbsp;Got back to it this morning and when entering the RSTLIB command I receive an error of &quot;Not able to allocate object TAP02.&quot; &nbsp;If I try to check the contents of the tape (with DSPTAP DEV(TAP02)) I receive &quot;Cannot allocate device TAP02.&quot; &nbsp;I don't know why I am receiving these errors. &nbsp;Can someone with more experience than me (and I am a definite newbie on the AS400) explain these error messages and provide some pointers? &nbsp;Thanks.

Got back to it this morning and when entering the RSTLIB command I receive an error of "Not able to allocate object TAP02."

As400 - not able to allocate tap02 ?

Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers. For large systems, the operating system makes sure that different programs and users running at the same time do not interfere with each other. The operating system is also responsible for security, ensuring that unauthorized users do not access the system. Operating systems provide a software platform on top of which other programs, called application programs, can run.
